TECHNICAL FIELD

The present utility model relates to an electronic device in anelevator, particularly to an elevator monitor.

BACKGROUND

The existing elevator control systems can generally exert simple controlon moving up and down and opening/closing of the door only and are notprovided with more advanced functions such as real-time monitoring anddanger monitoring. Moreover, the existing elevator control systems cangenerally observe the number of floor at the doorway of the elevator orin the car of the elevator only and can not observe the operating speedof the elevator car as it is moving up and down. However, the car of theelevator is liable to the phenomenon of abnormal drop in the process ofmoving up and down. When the elevator door fails with the result thatthe opening or the closing of the door is blocked, it will be impossibleto get the accurate information on floor immediately, and manualtroubleshooting or manual reporting will be required for obtaining data,thus resulting in a certain potential safety hazard and affecting theeffect of use and practicality.

Therefore, in view of the above-mentioned disadvantages of common priorart, the inventor carries out research and improvement on the foregoingdisadvantages and finally generates the present utility model.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Below, the technical solution in the embodiment of the present utilitymodel will be clearly and completely described in conjunction with thedrawings in the embodiment of the present utility model. Apparently, theembodiment described is only a part of the embodiments of the presentutility model and not all of the embodiments. Based on the embodiment inthe present utility model, all other embodiments obtained by thoseskilled in the art will fall within the scope of protection of thepresent utility model.

Embodiment 1

As shown in FIG. 1, an elevator monitor as described in this embodimentincludes an upper cover 1 and a bottom case 2, with the upper cover 1fixed to the opening position of the bottom case 2 and a control panel 3provided in the inner space of the bottom case 2. The control panel 3includes a PCB board 31, a floor interpretation processor 34, anelevating speed recording and analyzing processor 35, an AV line inlet36, a data line inlet 37, an AV line outlet 38, a data line outlet 39, acontrol switch 30, an LED indicator 33 and a buzzer 32, with the signalreceived by the data line inlet 37 input to the elevating speedrecording and analyzing processor 35 and processed by the elevatingspeed recording and analyzing processor 35 before being input to thedata line outlet 39, the buzzer 32 and the LED indicator 33respectively, and the signal received by the AV line inlet 36 input tothe floor interpretation processor 34 and processed by the floorinterpretation processor 34 before being input to the AV line outlet 38.
